--------------------------------------

             Summary: Provide more detailed metrics why asynchronous part of checkpoint is taking long time
                 Key: FLINK-17468
                 URL: https://issues.apache.org/jira/browse/FLINK-17468
             Project: Flink
          Issue Type: New Feature
          Components: Runtime / Checkpointing, Runtime / Metrics, Runtime / State Backends
    Affects Versions: 1.10.0
            Reporter: Piotr Nowojski


As [reported by users|https://lists.apache.org/thread.html/r0833452796ca7d1c9d5e35c110089c95cfdadee9d81884a13613a4ce%40%3Cuser.flink.apache.org%3E] it's not obvious why asynchronous part of checkpoint is taking so long time.

Maybe we could provide some more detailed metrics/UI/logs about uploading files, materializing meta data, or things that are happening during the asynchronous checkpoint process?
